Specification of Letters Patent.

CULTIVATOR,

Patented March 12, 1907'.

Application filed June 19, 1906. Serial No. 322,482.

To all whom t '11m/y concern.-

Beit known that I, LoUIs PARENTI, a citi- Zen of the United States,residing at Isleton, in the county of Sacramento and State ofCalifornia, have invented certain new and useful Improvements inCultivators, of which the following is a specification.

This invention relates to new and useful improvements in cultivators,and it particularly contemplates a device for use in cultivatingasparagus and similar vegetables.

The invention aims as a primary object to provide teeth-carrying framescapable of universal adjustment to adapt itself to the conditions andcircumstances of use.

It is a further object of the present invention to provide a device ofthe type set forth which shall be simple and inexpensive to manufacture,strong and durable, and eilicient and practical in use.

The detailed construction will appear in the course of the followingdescription, in which reference is had to the accompanying drawings,forming a part of this specification, like numerals designating likeparts throughout the several views, whereinn Figure 1 is a perspectiveview illustrating a cultivator constructedand arranged in accordancewith my invention. Fig. 2 is a top plan view thereof. Fig. 3 is aperspective view of a tongue-adjusting device employed in connectionwith the adjustable tooth-carrying frames, and Fig. 4 is a sideelevation thereof.

In the practical embodiment of my invention I employ a wheeled supportcomprising a bar 1 of substantial LJ shape formed with a horizontalupper portion 2 and downwardlydiverging legs 3, upon the ends of whichare journaled traction-wheels 4. The horizontal portion 2 of the bar 1passes loosely through lips 5, by which said bar is secured to a base orplatform 6, from which the appurtenant elements of the structure depend.A post 7, carrying a seat 8, is mounted upon the rear portion of theplatform 6. Mounted at each end of the platform 6 are straps 9 and 10,which project beyond said platform on each side thereof. Rods 11,arranged in spaced parallel relation to the platform 6, are mountedbetween the projecting end of the straps 9 and 10, and in thisdisposition said rods serve as elements of the hinge which forms apositive support for the depending cultivator-frame.

In the preferred embodiment of the invention cultivating-frames 12 and13 are arranged on each side of the plate 6 and are counterparts inconstruction, so that a description of a single frame and itsappurtenant elements will be applicable to both of the frames. The frame12 comprises an upper relatively stationary bar 14, carrying aperturedbrackets 15, which surround the rod 1l, adjacent thereto, and coacttherewith to form a hinge for the frame 12. The bar 14 has pivotalconnection at its ends with side bars 16 and 17, which are in turnunited at their lower ends by a bottom bar 18, to which they arepivoted. A central bar 19 is pivoted at its ends to the bars 14 and 18and is arranged upon said bars so as to be constantly parallel with thebars 16 and 17 in any adjustment thereof. The bars 16, 17, and 19 areprovided with teeth 20 of any approved form designed for the functionsabove set forth.

In their interconnected relation the several bars are strengthened by adiagonal bracebar 21, which serves as an adjusting element and to thisend has pivotal connection at its lower extremity, as at 22, at thepoint of union of the bars 16 and 18. The pivotal connection of theupperend of the bar 19 is adjustable and is formed by the bolt-and-nutfastening 23, which serves as a hinge or pivot for the bars 14 and 17and which passes through any one of apertures 24, arranged in axialseries in the upper portion of the bar 19, according to the adjustmentof the frame desired. The frame 12 is set in any position with relationto the base 6 by suitable adjusting elements provided for that purposeand to this end is provided with a bar 25, fulcrumed between the bars 17and 19 and arranged parallel to the bar 18. The bar 25 is provided withapertures 26, arranged in hori- Zontal series and designed individually,according to the adjustment of the frame, for the reception of anut-and-bolt fastening 27, by which connection is had with anangularly-disposed post 28, formed at its upper end with an aXial seriesof apertures 29. The post 28 projects through a slot 30 in anoutstanding bracket 31, carried by the base 6. The bracket 31 isprovided on each side of the slot 30 with registering apertures 32. Apin 33 passes through any selected one of the apertures 32 and 29 andforms a positive connection between the post' 28 and bracket 30, theapertures 32 and 29 being brought into individual registry according tothe suspen- IOO IIO

sion adjustment of the-framewith relation to the base 6.

The base 6 carries on: one side thereofl a longitudinally-arrangedU-shaped rack-bar 34, and the bar 1 carries a substantially verticallever 35, which is provided with. a sliding spring-pressed pawl 36,operated by a pivoted auxiliary handle 37. The Atongue 38, by which thedraft is established, passes loosely through a clip 39, secured to theforward portion of the base 6. As shown in Fig. 4, said' tongue isprovided at its rear end with 'an inclined or beveled underneath face40,

by which the position of the tongue with relation to the base6 iscompensated in any adjustment of said base. Said tongue carries at itsrear endy a projecting member L11,l provided with an eye through whichpasses a connection 42, designed to engage inv any selected one of aseries of apertures 43, varranged in a vertical post 44, rigidlycarriedupon the base 6 andwhich may be, if desired, an intergal part ofthe strap Q,

In practicalV use` the frames 12 and 13' are adjusted with a view tochanging their dimensions, and, proportionately, the'intervals betweenthe teeth 2() by the bar 2 1 in the manner above intimated. Adjustmentis effected relatively between the frames 12'and 13 and the base 6 atthe point of connection ofthe post 28 and bracket 30. The base 6'is inturn raised or lowered with the frames in any desiredadjustment thereof7by the proper movement ofthe lever 35, which is set in any selectedposition by the engagement of the pawl 36 with the rack-bar 34.

While the elements herein shown and described are well adapted to servethe functions set forth, it is obvious that various minor changes maybev mad'e in the proportions, shape, and arrangement of the severalparts without departing from the spirit and scope of my invention asdefined in the appendedr claims.

Havingl fully described my invention, I claim- 1. A device of the typeset forth embodying a longitudinal. base, a` wheeled support upon whichsaid base is carried, rectangular frames pivotally depending from saidbase on each side thereof, eachk of said frames comprising bars havingpivotal connection withl one another at their ends, means for adjustablyregulating the angular disposition. of said bars and means for raisingand lowering said frames to any selected fixed position- 2. A device ofthe type set forth embodying a base, a wheeled support uponv which saidbase is carried,- frames depending from said base on each side thereofand comprising interconnectedpivoted bars, means. for varyingA theangular relative disposition of said bars,r means for adjustablypositioning saidl frames withrelation, to said base, and a compensatingelement for said last-named means and' adjustable with relation thereto,depending on the adjustment of said firstnamed means.

In testimony whereof," Il affix my signature in presence of twowitnesses.
